Specification of Letters Patent.

Application filed December 23, 1928. serial No. 432,804.

To aZZ whom it may concern;

Be it known that I, CHARLES S. Pinion, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Magneto lie chargers; and'I do declare the :tollowin to be a full, clear, and exact description of the invention, such as will'enable otiiers skilled in the art to which it appertainsto make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to a magneto rcenergi-zing device; that is, to means for energizing the permanent magnets oi a'inagvehicle now manufactured by the Ford Motor Company of Detroit, Michigan.

This type of magneto includes a plurality of permanent magnets, approximately sixteen, and under certain conditions during use, the magnets become (ls-energized. Therefore, in order to restore the magneto to its efiiciency, new permanent magnets must be substituted or the magnets must be re-energized to their original condition. I-Ieretofore various attempts have been made to accomplish the desired result with more or less success but the success depends to a great extent upon the skill of the operator.

I have provided a i'e-energizing or recharging device which will eliiciently echarge the permanent magnets in an ex:- peditious manner. the device being ada jited to be operated without any special knowledge on the part of the operator and the construction is such that unitorm, satistactory results can be obtained.

In the drawings,

Fig. 1 is a perspective view of a device constructed in accordance with my invention, the magneto of conventional form be ing shown in side elevation and electrically connected to the device.

Fig. 2 is a wiring diagram of the device.

Fig. 3 is a sectional view through the instrument board, showing the manner of connecting one of the binding posts, and

Fig. 4: is a wiring diagram of a conventional form of ignition system.

Referring now to the numerals of reference:

1. iilesignatcs an instrument board which may consist of any suitable insulating material and which is I 2 mounted upon the standards or legs 3 to superpose the board above the floor The essential operating mechanism is carried bv the ii'isti'uinent board' the source of current supply may consist of a commercial line wire or any other source. In Fig. 2 the source of generation is indicated at 4-. the svmbol designating a generator. I i F The conductors 5 and 6 lead to the switch 1 on the instrument board 1, the switch being provided with the usual contacts 8 and 9. The contact 9 is in electrical connection with the rheostat 10, from which a conductorll leads to a swinging contact arm 12 drawings by insulated on the instrument boai'd and having a movable electric contact 13 to swing in an are over the circular series of contacts i l, electrically connected to the ring-shaped conductor 1%, which, in turn is connected to a conductor 15, leading to the binding post 16 on the instrument board. The contacts each comprise a head on the end of a shank 17, which passes through the instrument board and is secured thereto by a collar 18. there being a binding nut 19 bv means of which the conductor 14- may be tastened to the binding post, as will be well understood. it conductor 21 is shown as connected to the binding post 16 and to a binding post in circuit with the series of coils of the magneto the coils being grounded to the at: ease that the return circuit mar be connected at through the conductor 26 to binding post through conductor 28, amineter 29, back to contact 8 and through the switch to conductor 6 to the generator.

Between the live contacts let, that is, alternating therewith, are dead contacts 30 so that as the swinging contact 13 moves in the arc, said contact 13 will alternately pass over a live contact and dead contact,causing an intermittent, uniformly spaced interruption of the current; that is, there will be a uniform making and breaking of the current when the arm 12 is swung on its pivot a uniform rate of speed whereby the coils will become energized by current supplied from the generator 4.

supported upon a shelf- In actual practice the instrument board will be set up as shown in Fig. 1, with the conductors 21 and 26 ready to be applied to the binding post 22 and the ground re spectively and the rheostat 10 will be adjusted for the proper amperage which may be indicated on the ammeter 29. Then the swinging contact or crank 12 will be rotated about the axis of its pivot over the alternating live and dead contacts 14 and to cause a relatively rapid make and break of the circuit, resulting in an efficient recharging of the permanent magnets 31 of the magneto. As soon as the magneto has been properly charged, the connections 22 and 25 may be broken and the magneto will be ready to operate in the usualway.

The shelf 2 is adapted to carry a seat or rest consisting of the members 31 and 32 to receive a coil box 33, provided with contacts 34, 35 and 36 to rest against the con tacts 37, 38 and 39 in circuit with the bat tery through the conductors 40, 41, and 42. Interposed in the conductor 41 are the contacts 44 and 45, which are adapted to receive a spark plum The coilbox having been placed in position with the spark plug receiving contacts 44 and 45, the vibrators of the coils can be inspected and in case of necessity, adjusted upon the shelf 2 at the same time that the permanent magnets 23 are 'electricall connected to the instrument board for recharging.

It will be apparent from the foregoin that whenever the permanent magnets o the magneto need recharging or re-energizing, it will be only necessary to connect up the. connections 22 and 25 with the conductors 21 and 26, adjust the rheostat and swing the arm 12 about the contacts a sufficient number of revolutions to recharge or re-energize the magnets. Therefore, the magneto may be restored to operative con dition in an expeditious and convenient manner.

What I claim and desire to secure by Letters-Patent is:

In a device for recharging the permanent magnets of a magneto, a conductor adapted to be connected to one of the line wires of a commercial circuit and to the binding post of the magneto whereby current will pass direct from the commercial line to the bind ing post, a conductor adapted to be connected to the other line of the commercial circuit and to a rotating contact, spaced contacts over which the rotating contact may pass, and a conductor connecting all of the spaced contacts to a ground on the magneto frame. Y

In testimony whereof I afiix my si nature.

' CHARLES S. P ICE.
